The spectrum from a hydrogen vapour lamp is measured and four lines in the visible light range are observed. These lines are the
Elan Coil [88]

Answer:

10942249.24 m^{-1}

Explanation:

Rydberg's formula is used to describe the wavelengths of the spectral lines of chemical elements similar to hydrogen, that is, with only one electron being affected by the effective nuclear charge. In this formula we can find the rydberg constant, knowing the wavelength emitted in the transcision between two energy states, we can have a value of the constant.

\frac{1}{\lambda}=Z^2R(\frac{1}{n^2_{1}}-\frac{1}{n^_{2}^2}})

Where \lambda it is the wavelength of the light emitted, R is the Rydberg constant, Z is the atomic number  of the element and n_{1} n_{2} are the states where n_{1}.

In this case we have Z=1 for hydrogen, solving for R:

R=\frac{1}{\lambda}*(\frac{1}{n^2_{1}}-\frac{1}{n^_{2}^2}})^{-1}\\R=\frac{1}{658.9*10^{-9}m}*(\frac{1}{2^2}-\frac{1}{3^2}})^{-1}\\R=1.52*10^6m^{-1}*(\frac{36}{5})=1.09*10^7 m^{-1}=10942249.24m^{-1}

This value is quite close to the theoretical value of the constant R=10967758.34 m^{-1}

If you were to apply a force of 15N to a medicine ball with a mass of 5kg, what would its acceleration be
yaroslaw [1]

Given that

Force (F) = 15 N ,

mass (m) = 5 Kg ,

acceleartion = ?

              We know that, From Newtons II law

                      F = m. a

                    15 = 5 × a

                     a = 15÷ 5

                       a = 3 m/s²

acceleration of the ball is 3 m/s²
